Intel XEON 5500 / 7400 Performance Benchmark-Tests

webadmin@intel.com — Tue, 24 Nov 2009 22:10:03 GMT

Hello,

could anyone explain why the 6core Intel Xeon 7400 series isn't so much faster in the tpmC-benchmarks as the Intel Xeon 5500 4core series?

With 4 CPUs each with 6cores the Intel Xeon 7400 series (639,253 tpmC) should be much faster in the tests as the server system with 2 CPUs each with 4cores of the Intel Xeon 5500 series (631,766 tpmC).

What could be reasons why a customer should choose Intel Itanium II CPUs for an Oracle Database environment? Are there any advantages or disadvantages by using the Intel Xeon 5500 or 7400 series?

Thanks for your answers

Daniel

Copying the memory controller means of DMA.

webadmin@intel.com — Tue, 24 Nov 2009 15:52:51 GMT

Hello!
There were some problems when programming DMA(bas. 8237А) controller in copy memory mode(memory-to-memory). I ask for your help.
I'm trying to copy the physical memory. You must perform the second movement of the memory controller, as the x16 registers and the address range 16M. First, try to run through the first movement of memory controller as a test.
To verify the results of operations and loading initial data used by the mapping of the first page of physical memory by the function(OS: NT, Protected mode, Ring 0) MmMapIoSpace(), but not in this sense.
My Motherboard: Gigabyte GA-8IPE1000MK, CPU: P4
After reviewing the documentation on the controller has written the following code.

;

LATCHB EQU 83H
CLEAR_F EQU 0CH
CH0_A EQU 00H
CH1_A EQU 02H
CH0_C EQU 01H
CH1_C EQU 03H
MODE EQU 0BH
CMMD EQU 08H
MASKS EQU 0FH
REQ EQU 09H
STATUS EQU 08H

TRANSMIT PROC
PUSHFD ; Save IF
CLI
XOR AX,AX
OUT LATCHB,AL ; Page
OUT CLEAR_F,AL

OUT CH0_A,AL ; Source: 0x0000
OUT CH0_A,AL

MOV AL,16
OUT CH1_A,AL ; Destination: 0x000F
XOR AX,AX
OUT CH1_A,AL

MOV AL,32
OUT CH0_C,AL ; Length
XOR AX,AX
OUT CH0_C,AL

MOV AL,32
OUT CH1_C,AL
XOR AX,AX
OUT CH1_C,AL

MOV AL,88H
OUT MODE,AL ; Chanel 0, read, increment, blocks.

MOV AL,85H
OUT MODE,AL ; Chanel 1, write, increment, blocks.

MOV AL,1
OUT CMMD,AL ; Memory-to-memory

MOV AL,0CH
OUT MASKS,AL ; Unmask chanels 0, 1

; MOV AL,4
; OUT REQ,AL ; Request to chanel 0.
MOV AL,5
OUT REQ,AL ; Request to chanel 1.
@@:
; IN AL,STATUS
; TEST AL,1
; JZ @B
POPFD ; Restore IF
RET
TRANSMIT ENDP

;

As a result, this code does not work. The memory is filled with the value 0xFFFF.. The documentation for this mode(memory-to-memory) is described very briefly. Perhaps this mode is not supported..

I would like to see a working example or a detailed description of the programming mode.

Thank.

Core i7 920 memory / cache problems

webadmin@intel.com — Tue, 24 Nov 2009 13:11:41 GMT

Hi,my Core i7 acts stange now and then.

It seems to hold stored information and present it while going for a next action.

For instance: when I change my monitorview in a 3D program I first get a flash of a stored image that I created before.

Something wrong with memory tasks.

In the configurationwindow / Details / Energiestatus -I found a little difference for the Cores

Could the problem be something with S2 ?

It says S2-> Not prescribed.

Al the other S0 S1 S3 S4 S5 have their energie given at D0 or D3

QPI voltage question - is mine too low?

webadmin@intel.com — Tue, 24 Nov 2009 02:54:06 GMT

I have a DP45SG with a Core 2 Duo E8400. Intel's Desktop Control Center shows my QPI Voltage at 1.05 and that this voltage is in the orangish-red area on my Monitoring gague. I'm not terribly familiar with QPI and how it fits into things, except that it's supposed to replace the FSB. I know that I'm suppose to have a QPI somewhere in the 1.12-1.15 range. Is this true? Do I have a problem since my QPI voltage is low?

I'm not experiencing any performance-related issues, other than the occasional single beep followed by a very short (almost cut off) second beep from the motherboar'd speaker about once or twice per day - still haven't figured that one out.

Thanks,

What is the release date for Arrandale Microprocessors?

webadmin@intel.com — Mon, 23 Nov 2009 02:20:33 GMT

Hi everyone,
I'd like to know about the release date for Arrandale Microprocessors,

Many people are waiting for these Arrandale processors after reading the rumors in some websites, including myself.

There are rumors that Intel will release on January 2010, is it True?

Does anyone (Perhaps from someone who works for Intel?) know the exact date??

Please let us know. Thanks!

Xeon Paxville MP minimum requirement ?

webadmin@intel.com — Sun, 22 Nov 2009 00:47:22 GMT

Hye,

I got an Xeon 7041 (only one - it's for an non-profit usage) and I would like to know by which chipset it would be supported.

I know that the accurate is E8500 but I have only an SE7520 mobo. Is there any dual socket server board that I can use?

What is the power supply needed too (heavily usage with boinc)?

Regards

Emmanuel

zeon e5472-anybody know core peci bus safe operating range??

Broken LGA 775 F2 pin

webadmin@intel.com — Wed, 18 Nov 2009 02:40:30 GMT

The F2 pin on my GA-EP45-UD3P's CPU socket is broken, will it still work with any of the LGA775 processors? I see that the pin is GTLREF2 Power/Other for quad core processors and FC5 Power/Other for duo core and celeron processors. It'd be a pitty to let this beautiful board go into the trash bin because of one pin!! Your advice would be appreciated.

processor comparison for TV tuner card purchase

webadmin@intel.com — Tue, 17 Nov 2009 03:24:47 GMT

Due to my D100 DirecTV receiver pooping out I purchased a DirecTV HD receiver from Best Buy (does not record). It has HDMI, component, s-video, and composite outputs. Lacking is an F-connector output now. When I purchased my Dell XPS Gen5 Windows XP MCE 2005 desktop in 2005 it included an Emuzed TVT3 TV tuner card. It only has an F-connector and s-video inputs including audio inputs. Sometimes I record an old movie or want to record a TV show. I've extended my desktop onto a CRT TV and I use it as a monitor to replay what I may have recorded. However, the quality of the recording via Media Center is poor. I have located a TV tuner card made by AVerMedia AVerTV HD DVR MTVHDDVRR PCI-Express x1 Interface which shows two HDMI connectors. I am aware of the HDMI recording restrictions. At my age I have no interest in recording and/or bootlegging movies. I only want to improve the video of what I may legally record and watch at a latter time. I can't determine from the poor description if they are two inputs or one in and one out. The description specifies system requirements which notes Intel Core 2 Duo E6600 2.4GHz or equivalent AMD CPU. My processor is an Intel Pentium D 830 (3.0GHz) w/Dual Core Technology (whatever that is). I would appreciate knowing if my computer is capable of supporting this AVerMedia TV tuner card before purchasing? p.s. I read an article online regarding a KWorld TV tuner card with component video inputs but I can't locate where I could purchase one. Thanks for any help.
